Abstract
Because of high performance in mechanical properties and low density, carbon reinforced plastic (CFRP) is widely used as structural material for airplane, various kind of sports gear and premium automobile. Generally, production rate of CFRP structure is lower than conventional materials such as steel or aluminum alloy because the thermosetting process by using autoclave requires long cycle time. Recently, thermo-elastic resin is used as CFRP matrix to reduce the cycle time, press molding of CFRP within just one minute's time is achieved. The thermal properties of thermoelastic-resin is quite different from the thermosetting resin commonly used in CFRP, huge burr formation during trimming operation is often observed. In this study, the suitable machining parameters were proposed for milling through the machining experiments and thermal observation.
